I did this workout yesterday. The first time I did it (a month or so ago),I had to do the 20 & 30 rep sections in increments of 10, and even then I was beat.
Yesterday, I threw in box jumps for the hell of it.
I was happy to see improvement. I was able to do the 10 & 20 rep sections all the way through. For the 30 rep, I still had to break it down (deadlifts: 15-10-5, push-ups: 15-15, kb swings 22-8).
Super tired at the time, but got over it quickly. So my goal for the next time I do this is to get through the 30 reps in one shot.
Thank you Femme Fabulous for sharing this awesome workout.

You added box jumps!!! Damn girl you are hardcore! I found this workout hard the first time too. If I remember correctly I had to go and have a lie down afterwards 🙂 Thanks for sharing the workout BTW.
Yep, exhausting but a lot of fun too (if your idea of fun leans toward the side of brutality I suppose) :).
